Defiance receivers are made from 416 stainless and are very corrosion resistant. If left “bare,” they will resist corrosion in most all conditions. Our bolts are 4340 chrome moly, which is susceptible to corrosion. The smooth finish we provide helps to repel moisture, but if you want added protection against corrosion, you have options.
- Be diligent with your maintenance by cleaning, drying, and lubricating the bolt. A bolt “in the white” will resist rust very well if properly maintained.
- Defiance offers Black Nitride, a molecular coating that, adds lubricity, and surface hardness, as well as turns the steel a rich black colour without adding measurable thickness. This adds an additional cost as well as a slightly longer lead time.
- 4340 will accept bluing or Parkerizing. (Both are black or dark gray and help resist rust.)
- Cerakote is an option for protecting your action and bolt. However, Cerakote adds thickness to the surface of the metal and we maintain tight clearances in our actions, so Cerakote must be properly applied by a certified applicator which can be found on Cerakote’s website. We recommend that you do NOT apply Cerakote to the bolt and the lug raceways in order to prevent binding of your bolt.
